The last weeks I have been thinking over and over and over....

And the solution to this problematic issue is:

To cut the IRQ wires on the motherboard (where they appear at the PCI slot), and to solder the correct INT #x to the slots that need the same IRQ, hence all these soldered PCI slots will use the same IRQ!

I imagine it would be possible to use more than 3 CW cards then....

This is just something I have thought about a long time, but I'm not responsible if someone fries their mobo's!

Hello.

Soldering on the motherboard ey ?
I strongly believe that this is something one should NOT try.

And is it really possible? I mean.
I thaught the curcuits where "layered".

I mean, a motherboard is constructed in this way.
Lots of curcuits over one an other, in layers. Am i wrong ?

Anyway..about your ide'a....im not sure if it would work. Mabye it would. Im technicall but when it comes to these kinds of operations...i really don't know.

Hey planetZ !!! Somenone out there with a degree in "Motherboard developments" ?!?

Certainly not. About 13+ layers for most modern MOBOs!

Need a damn steady hand...

Side note: the tracks on modern MOBOs aren't really conductors, they are more like waveguides due to the incredibly high frequencies used. If the designers make the bends in the tracks too sharp, they become aerials!

Mad quantum effects, innit.

Royston

The real question is, can SFP address more than 3 boards?

I think the answer is no, even if you modify your mobo, which is risky at best.

I would certaintly say so !!

With these beautyfull words we rest our case.....for time being

And people...
If there is anyone here thinking about doing some finetuned soldering on there MOBO's.....keep that hand steady !!!

I have 2 Powerpulsar and 1 Pulsar SRB with their IRQ automatically assigned by Windows 2000... WITHOUT ANY PROBLEM AND ANY CONFIGURATION AT ALL.

I just plugged them in empty PCI slots.

and you're sure you don't have a mac or so?

(what a stupid joke )

Heh, it's not impossible to do what I said in my starting post, but, there is a great deal of technical knowledge to to it....

Take a "barebone" (no extra's) mobo, cut the irq wires *at* the destination, solder the wire (s), done!

But, be sure that it's not sharing other signals on the connectors!

Many mobo's is hardwired like this from the factory; like my Asus P4C800-E Deluxe, PCI 1 & 5 is set to share irq....

This means if you have cards that need to have the same irq, put them there!

I have put two of my UAD-1's there, in 1 & 5.
My TC Powercore 01's is in 2 & 4, while the Pulsar II is in the 3'rd....

This isn't a "barebone" mobo, it was just taken into this as an example....

.... And I haven't soldered anything yet, I'm just searching for a barebone mobo that suits my needs, as I want to put 2 x Pulsar II's, 2x Pulsar1's there, running in SFP mode.

The Scope SRB I want to put where one of the Pulsar II's is today, the before mentioned PCI 3. What's keeping me from doing it now, is that I just recently bought the Scope SRB secondhand, and need to transfer plugins to this, and I need this to run in XTC mode only ....

If I get all this done, I would have a great "synth station" at hand, in SFP mode, and running a VST host at the same time with some VSTI's, while my main computer running Nuendo do the mixing with all these great DSP cards.

I must admit that soldering on a mobo, and modify it is not for everyone.

Anyone tried to use more than 3 CW cards in one machine here?

What people still do, is changing BIOS chips, soldering to take out the bad one, and soldering a new one removed in the same way, from an older MOBO. This is widly used in poor countries, where people must make with what they have.

It is said that: "There is nothing more intelligent than hunger".

Hmm, not sure what you mean....

Explain please
